High Performance AC Gear Motors

  • 100 W (1/8 HP)

Parallel Shaft Gear Motor

High Efficiency at a Maximum of 77.8%*

Specialized components and optimal magnetic design are used to make high efficiency three-phase motors with a maximum efficiency of 77.8%*. Motors are fanless, with increased motor output and significant loss reduction.
*200 W (1/4 HP) KIIS Series meets IE4 Standards.

High Efficiency Gear Motors

High Performance

Characteristics have been improved through pursuit of the specifications required for the three-phase motor and a review of the design to create a high-performance motor with little speed reduction even with a large load.

High Performance AC Gear Motors

Power Consumption Reduced by up to 10%

Compared to a conventional 90W product under the same conditions, power consumption is reduced by a maximum of about 10%, contributing to the the equipment's energy savings.

Improved Power Consumption


Increased Motor Output

Output power of 100 W (1/8 HP) in a 90 mm (3.54 in.) frame size is achieved through increased efficiency. An overall length 15mm (0.59 in.) shorter than the conventional product contributes to equipment downsizing.

Downsized Motor

Fanless

With reduced loss, there is less heat generation in the motor, so the cooling fan is no longer needed. With no cooling fan, dust is not blown around.

Fanless Motor


Equipped with an Easy-to-Wire, Slim Body Terminal Box

This new shape of terminal box is designed to make wiring the terminal block easier. It has a slim body, with a cable outlet that can be rotated in 90° increments for 4 possible directions.

Terminal Box Type

IP66-Compliant Drip-Proof Specification

The seal structure for the motor, gearhead and terminal box components has been strengthened. The terminal box type* is compliant with the IP66 degree of protection.

*Excluding installation surface of the round shaft type.

IP66:
The IP indication that shows the watertight and dust-resistant performance are specified under IEC 60529 and IEC 60034-5.

Main Specifications:

  • Material
    Case and terminal box: Aluminum
    Output shaft: S45C
    Screws: Stainless steel (externally facing screws only)
  • Surface Treatment
    Case and terminal box: Painted (excluding installation surface)

Best Characteristics Achieved when Combined with Inverter

Wide Range of Speeds

Speed can be controlled over a wide range using an inverter, from 3~120 Hz*. Also, with improved characteristics, high torque can be exerted even at low speeds.

Wide Speed Range

Improved Speed Stability

Because it is a high-performance motor with little speed reduction even with a large load, stabilized speed control is possible.

Speed Stability

Handles High-Speed Rotation (Round shaft type)

Creep-free bearings, etc. are used in the round shaft type and components capable of handling high-speed rotation have been selected and designed for inverter control.

High Permissible Load

 


High Strength

Permissible overhung load and permissible thrust load have doubled compared to conventional products*. This has been made possible by increasing the case rigidity, adding larger diameter bearings and improved gear strength through heat treatment.

*The same in some products.

High Strength Gears

Permissible overhung load and permissible thrust load have doubled compared to conventional products. (40 W vs. 25 W comparison).

Overhung Load


Long Life

The gearhead ball bearing diameter has increased, resulting in doubling the life of the gearhead (10,000 hours compared to the rated life of 5,000 hours for conventional gearheads). Performing maintenance has decreased as a result of the longer life.

The rated life has doubled compared to conventional products.

Long Life

Quiet

The motor and gearhead noise (meshing sound) has decreased by approximately 6 dB compared to conventional motors. Put into perspective, the noise level has decreased by 50%.

The gearhead noise has been decreased by 6 dB compared to conventional products.

Quiet Operation


Combination Type

The motor and gearhead come pre-assembled and ready to install. Concerns of damage resulting from improper gearhead installation leading to abnormal noise in the shaft are eliminated.

Easy installation thanks to the pre-assembled motor and gearhead.

Combination Type Gear Motor

High Gear Ratio

Decimal gearheads were once required for gear ratios above 1:180. Now a single gearhead is available (up to 1:360), saving space and reducing components and costs.

No decimal gearhead is required, allowing the total length to be shortened.

Decimal Gear

Tap Output Shaft

An end tap has been integrated into the tip of the output shaft of gearheads, with a rated output power of 25 W (1/30 HP) and higher. The tap can be used to prevent pulleys and other transmission mechanisms from slipping.

Tap Shaft

Right-Angle Hollow Shaft and Parallel Shaft Gears

  • 100 W (1/8 HP)
  • 200 W (1/4 HP)

Right-Angle Shaft Gear Motor

The right-angle geared type provides high strength through the use of hypoid gears and an integral structure of the motor and gears.

Benefits of Using the Right-Angle Geared Type

Conveyor Motor
Space Saving

Hollow Shaft Gear Conveyor

Because the output shaft of the gear is vertically in the middle of the installation surface, it is possible to change the installation direction horizontally. Installation to suit the equipment can be selected.

Right-Angle Gear Mounting


Electromagnetic Brake Type

  • 100 W (1/8 HP)

Brake Motor

These motors have a "power off" activated type electromagnetic brake to hold the load in position when the power is cut off.

Ideal for Applications Required Load Holding

This configuration is ideal for vertical applications where the load must be held.
